Description
Technical Field
[0001] This invention relates to the field of mining conveyor technology, specifically a mining conveyor with a safety protection structure. Background Technology
[0002] A mine refers to an independent production and operation unit that extracts ore within a certain mining boundary. A mine mainly includes one or more mining workshops (or pitheads, mine shafts, open-pit mines, etc.) and some auxiliary workshops. Most mines also include ore dressing plants (coal washing plants).
[0003] Conveyors can be classified according to their operation mode as follows: integrated loading and unloading conveyors, belt conveyors, screw conveyors, bucket elevators, roller conveyors, plate chain conveyors, mesh belt conveyors, and chain conveyors. Belt conveyors are currently the main method for conveying bulk materials.
[0004] In mines, mined ore needs to be transported to the surface, and conveyors are used to transport the ore, which includes coal. Coal can catch fire during transportation due to natural or human causes. Natural causes are usually lightning strikes or excessive and dense coal dust causing fires. Unlike ordinary fires, there are many combustible materials (coal) around the mine. If the tunnel is blocked by heat and smoke and oxygen deficiency occurs, it usually causes serious casualties.
[0005] To prevent coal mine conveyors from being struck by lightning, lightning rods are installed far away from the mine. However, lightning rods are not 100% effective at preventing lightning strikes. Ball lightning strikes are unpredictable and can render lightning rods ineffective, allowing the coal mine to be struck by ball lightning, causing fires and safety accidents. Therefore, it is essential to design a mine conveyor with a safety protection structure that is highly fire-resistant and has strong fire-extinguishing capabilities. Summary of the Invention
[0006] The purpose of this invention is to provide a mine conveyor with a safety protection structure to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a mine conveyor with a safety protection structure, comprising a support and protection structure and a transmission structure. The support and protection structure includes a protective mesh frame and a support bracket. The transmission structure is located inside the support and protection structure and includes a first stepper motor, a conveyor drum, a rolling drum, and a conveyor belt. A safety protection structure is provided on the upper side of the support and protection structure. The safety protection structure is a mirror image of the front and rear sections with identical structures. The safety protection structure includes a water tank, a water pump, a main water pipe, several support blocks, several branch water pipes, a booster pump, a straight water pipe, and a control box. The water tank is fixedly connected to the upper side of the protective net frame. The water pump is located on the left side of the water tank, with its input end connected to the water pipe in the water tank. The main water pipe is fixedly connected to the output end of the water pump. Several support blocks are evenly fixed to the lower side of the main water pipe, and several branch water pipes are fixedly connected to the rear side of the main water pipe. The booster pump is located at the junction of the branch water pipe and the main water pipe. The straight water pipe is fixedly connected to the lower side of the branch water pipe, and the control box is fixedly connected to the upper side of the straight water pipe. The control box is divided into an upper and lower layer. A second stepper motor is fixedly connected to the upper layer of the control box, and the second stepper motor has a first... The signal receiving module includes a programming controller located on the front side of the second stepper motor. The programming controller is fixedly connected to a control box. Inside the control box, on the lower layer, are two second gears and one first gear. A first drive shaft is located between the first gear and the second stepper motor. One end of the first drive shaft is connected to the output end of the second stepper motor via a coupling. The other end of the first drive shaft passes through the inner wall of the control box and is fixedly connected to the first gear. One end of the second drive shaft is fixedly connected to the lower side of the second gear. The other end of the second drive shaft passes through the upper end of a straight water pipe and is fixedly connected to a rotating disk. The rotating disk... The upper end is provided with a sliding groove. The rotating disk has three second through holes evenly arranged inside. A first through hole is evenly arranged at the included angle between two of the second through holes. A water spray head is fixedly connected to the lower side of each second through hole. A spray nozzle is fixedly connected to the lower side of the first through hole. A fixing ring is fixedly connected to the lower side of the straight water pipe. The middle of the fixing ring is open. The rotating disk can be installed inside the fixing ring. The lower end of the straight water pipe is rotatably connected to the rotating disk. The second stepper motor can control the rotation of the rotating disk by rotating it. An infrared thermometer is provided on the lower side of the control box. The infrared thermometer is fixedly connected to the branch water pipe.
[0008] The present invention further illustrates that the protective net is installed on the upper side of the support frame, and the support frames are bolted together.
[0009] The present invention further illustrates that the output end of the first stepper motor is fixedly connected to the inside of the conveyor cylinder via a transmission shaft. The conveyor cylinder is located at both ends inside the conveyor belt. The outer side of the conveyor cylinder is slidably connected to the inside of the conveyor belt. Both the front and rear ends of the conveyor cylinder are connected to the bracket by bearings. Several rolling cylinders are located inside the conveyor belt. Both the front and rear ends of several rolling cylinders are connected to the bracket by bearings.
[0010] The present invention further illustrates that a scraper is provided on the right side of the conveyor belt, the scraping opening of the scraper is in contact with the surface of the conveyor belt and the front and rear ends are fixedly connected to the inside of the bracket.
[0011] The present invention further illustrates that baffles are provided on both the front and rear sides of the conveyor belt, and the baffles are fixedly connected to both sides of the support.
[0012] The present invention further illustrates that a first sealing ring is provided at the upper opening of the straight water pipe, and a second sealing ring is provided inside the sliding groove.
[0013] The present invention further explains that when the rotating disk is not rotating, all three second through holes are blocked by the lower end of the straight water pipe and cannot pass water. The first through hole is interconnected with one of the third through holes and can pass water. The other two third through holes are blocked by the upper end of the rotating disk. Indirectly, at this time, none of the three spray heads can pass water, but the spray head can pass water.
[0014] The present invention further explains that when the rotating disk rotates 30 degrees, the three second through holes and the three third through holes are interconnected and can pass water, while the first through hole is blocked by the lower end of the straight water pipe and cannot pass water. Indirectly, at this time, all three spray heads can pass water, but the spray nozzle cannot pass water.
[0015] The present invention further illustrates that the water pump, the first stepper motor, the second stepper motor, the programmable controller, and the infrared thermometer are all electrically connected to an external power supply. The infrared thermometer has an internal transmission signal module and a temperature detection module. The infrared thermometer is electrically connected to the temperature detection module. The temperature detection module is electrically connected to both the pressurization pump and the internal transmission signal module of the infrared thermometer. The internal transmission signal module of the infrared thermometer is connected to the receiving end of the programmable controller. The two signal output terminals of the programmable controller are respectively connected to the signal input terminals of the first stepper motor and the second stepper motor.
[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: By installing protective netting, baffles, and scrapers, foreign stones can be blocked from entering, and ore will not fall from the conveyor belt into the conveyor structure, causing transmission failure, thus achieving a good protective effect. By equipping the system with spray nozzles and a booster pump, the water volume can be increased and the water flow can be made more rapid, thus enabling faster fire extinguishing and achieving a strong fire extinguishing effect. By installing branch water pipes, booster pumps, and infrared thermometers, the fire source can be detected quickly, and water can be sprayed quickly and in a concentrated manner, achieving the effects of precise fire extinguishing and water conservation. By installing spray nozzles, the spray generated can suppress coal dust in the air, preventing excessive coal dust from spontaneously combusting due to high temperatures, thus avoiding fires, safety accidents, and property damage, achieving a high fire resistance effect.

[0019] Please see Figure 1-8 The present invention provides a technical solution: a mine conveyor with a safety protection structure, including a support and protection structure 1 and a transmission structure 5. The support and protection structure 1 includes a protective net frame 2 and a support 4. The transmission structure 5 is located inside the support and protection structure 1 and includes a first stepper motor 6, a conveyor cylinder 7, a rolling drum 8 and a conveyor belt 9. A safety protection structure 12 is provided on the upper side of the support and protection structure 1.

A booster pump 26 is located at the junction of the branch water pipes 17 and the main water pipe 13. The input end of the booster pump 26 is fixedly connected to the main water pipe 13. The output end of the booster pump 26... The end is fixedly connected to the branch water pipe 17. The booster pump 26 can pressurize the incoming water, making the slow-flowing water flow faster after being pressurized by the booster pump 26. The straight water pipe 18 is fixedly connected to the lower side of the branch water pipe 17. The control box 19 is fixedly connected to the upper side of the straight water pipe 18. The control box 19 is divided into an upper layer and a lower layer. The upper layer of the control box 19 is fixedly connected to the second stepper motor 20. The second stepper motor 20 is equipped with a first signal receiving module, which can perform precise angle rotation by receiving signals transmitted by the programmable controller 21. The second stepper motor 20 and the first stepper motor 6 are based on the same principle. The first stepper motor 6 is equipped with a second signal receiving module. The front of the second stepper motor 20 is equipped with... A programmable controller 21 is fixedly connected to the control box 19. The programmable controller 21 contains a first signal transmitting module and a second signal transmitting module. The programmable controller 21 can transmit motor angle rotation signals and motor stop signals through manual programming. The programmable controller 21 also contains a second signal receiving module. Inside the control box 19, in the lower layer, are two second gears 24 and one first gear 23. The first gear 23 meshes with each of the two second gears 24. Clockwise rotation of the first gear 23 simultaneously controls the counterclockwise rotation of the two second gears 24. The rotation angles of the first gear 23 and the second gear 24 are the same. A first drive shaft 22 is located between the first gear 23 and the second stepper motor 20. One end of the first drive shaft 22 is connected to the output end of the second stepper motor 20 via a coupling. The other end of the first drive shaft 22 passes through the inner wall of the control box 19 and is fixedly connected to the first gear 23. One end of the second drive shaft 25 is fixedly connected to the lower side of the second gear 24. The other end of the second drive shaft 25 passes through the upper end of the straight water pipe 18 and is fixedly connected to the rotating disk 37. The upper end of the rotating disk 37 is provided with a sliding groove 34. Three second through holes 35 are evenly provided inside the rotating disk 37. The included angle between each second through hole 35 is 30 degrees. A first through hole 33 is evenly provided between two second through holes 35. A spray head 31 is fixedly connected to the lower side of each second through hole 35. A spray head 32 is fixedly connected to the lower side of the first through hole 33.The lower end of the straight water pipe 18 has a second drive shaft 25 through hole in the middle and three third through holes 36 evenly arranged. The included angle between each third through hole 36 is 30 degrees. A fixing ring 29 is fixedly connected to the lower side of the straight water pipe 18. The middle of the fixing ring 29 is open, and a rotating disk 37 can be installed inside the fixing ring 29. The fixing ring 29 presses the upper and lower ends of the rotating disk 37 tightly to prevent the rotating disk 37 from falling downward. The lower end of the straight water pipe 18 is rotatably connected to the rotating disk 37. The second stepper motor 20 can control the rotation of the rotating disk 37 by rotating it. The lower side of the control box 19 is provided with An infrared thermometer 27 is fixedly connected to a branch water pipe 17. The output port of the infrared thermometer 27 is pointed towards the location of the coal mine. The principle of the infrared thermometer 27 is that objects with temperatures above absolute zero emit infrared radiation due to their molecular motion. After the infrared detector converts the power signal of the radiated object into an electrical signal, the output signal of the imaging device can perfectly simulate the spatial distribution of the object's surface temperature. This signal is processed by the electronic system and transmitted to the display screen, resulting in a thermal image corresponding to the object's surface heat distribution. Using this method, it is possible to achieve long-distance thermal imaging and temperature measurement of a target, and to analyze and judge its performance. Compared to contact temperature measurement methods, infrared thermometry has advantages such as fast response time, non-contact operation, safety, and long service life.
[0021] The protective net frame 2 is located on the upper side of the support 4. The protective net frame 2 can completely cover the transmission structure 5 to protect the transmission structure 5 and prevent stones from falling into the transmission structure 5 and causing transmission failure. Each support 4 is bolted to each other.
[0022] The output end of the first stepper motor 6 is fixedly connected to the inside of the conveyor cylinder 7 via a drive shaft. The conveyor cylinder 7 is located at both ends inside the conveyor belt 9. The outer side of the conveyor cylinder 7 is slidably connected to the inside of the conveyor belt 9. Both the front and rear ends of the conveyor cylinder 7 are connected to the bracket 4 by bearings. The conveyor cylinder 7 can drive the conveyor belt 9 to slide. Several rolling cylinders 8 are located inside the conveyor belt 9. Both the front and rear ends of the rolling cylinders 8 are connected to the bracket 4 by bearings. The rolling cylinders 8 can be used to support the conveyor belt 9 and assist the conveyor belt 9 in sliding.
[0023] A scraper 11 is provided on the right side of the conveyor belt 9. The scraping nozzle of the scraper 11 contacts the surface of the conveyor belt 9 and its front and rear ends are fixedly connected to the inside of the bracket 4. The scraper 11 can contact the conveyor belt 9 through the scraping nozzle to scrape off the small particles stuck to the surface of the conveyor belt 9, preventing them from falling into the equipment when sliding to the bottom, which could easily cause equipment failure over time.
[0024] Baffles 10 are provided on both the front and rear sides of the conveyor belt 9. The baffles 10 are fixedly connected to both sides of the support 4. The baffles 10 can block the ore and prevent the ore from falling into the inside of the transmission structure 5 during transportation.
[0025] A first sealing ring 28 is provided at the upper opening of the straight water pipe 18, and a second sealing ring 30 is provided inside the slide groove 34. The sealing rings can prevent water leakage caused by the rotation of the second drive shaft 25.
[0026] like Figure 9 When the rotating disk 37 is not rotating, all three second through holes 35 are blocked by the lower end of the straight water pipe 18 and cannot pass water. The first through hole 33 is interconnected with one of the third through holes 36 and can pass water. The other two third through holes 36 are blocked by the upper end of the rotating disk 37. Indirectly, at this time, all three spray heads 31 are not passing water, and only the spray head 32 can pass water.
[0027] like Figure 10 When the rotating disk 37 rotates 30 degrees, the three second through holes 35 and the three third through holes 36 are interconnected and can pass water. The first through hole 33 is blocked by the lower end of the straight water pipe 18 and cannot pass water. Indirectly, at this time, all three spray heads 31 can pass water, only the spray head 32 cannot pass water.
[0028] The water pump 14, the first stepper motor 6, the second stepper motor 20, the programmable controller 21, and the infrared thermometer are all electrically connected to an external power supply. The infrared thermometer 27 has a third signal transmitting module and a temperature detection module inside. The temperature detection module is preset with the ignition temperature of the coal mine. The pressurizing pump 26 has a third signal receiving module inside. When the infrared thermometer 27 detects the ignition temperature of the coal mine, the temperature detection module is connected to the pressurizing pump 26 and the third signal transmitting module respectively. The temperature detection module can control the pressurizing pump 26 and the third signal transmitting module to be powered on or off. The third signal transmitting module will transmit a signal to the programmable controller 21 once when it is powered on or off. The third signal transmitting module is connected to the second signal receiving module of the programmable controller 21. The first signal transmitting module and the second signal transmitting module of the programmable controller 21 are respectively connected to the second signal receiving module of the first stepper motor 6 and the first signal receiving module of the second stepper motor 20. The programmable controller 21 is programmed with a 30-degree rotation angle and a stop rotation. The 30-degree rotation angle signal corresponds to the second stepper motor 20, and the stop rotation signal corresponds to the first stepper motor 6.
[0029] Example 1: In hot weather, the water pump 14 is turned on, and the water in the water tank 15 is transmitted through the main water pipe 13 to the interior of each branch water pipe 17. Then, from the interior of each branch water pipe 17, it flows to the straight water pipe 18, through one of the third through holes 36, and into the interior of the first through hole 33 of the rotating disk 37. Finally, it is sprayed out from the spray head 32. The spray formed can suppress coal dust in the air and prevent excessive coal dust from spontaneously combusting due to high temperature, thereby causing fire, safety accidents and property damage, and achieving a high fire resistance effect.
[0030] Example 2: To prevent spontaneous combustion of coal when a ball lightning strikes a coal mine on conveyor belt 9, causing one of the coal mines to instantly reach its ignition point, an infrared thermometer 27 detects the ignition point temperature of the coal mine. The temperature detection module inside the infrared thermometer 27 is activated. At this time, both the pressurization pump 26 and the third signal transmission module inside the infrared thermometer 27 are energized through the temperature detection module. The pressurization pump 26 begins to pressurize the water, and the water flow becomes more rapid. The third signal transmission module sends a signal to the programmed control... The device 21 transmits signals, and the programmable controller 21 transmits signals to the first stepper motor 6 and the second stepper motor 20 respectively. The first stepper motor 6 receives a signal to stop rotating, and the second stepper motor 20 receives a signal to rotate 30 degrees. At this time, when the rotating disk 37 rotates 30 degrees, the three second through holes 35 and the three third through holes 36 are interconnected and water can pass through. The first through hole 33 is blocked by the lower end of the straight water pipe 18 and does not pass through. Indirectly, at this time, all three spray heads 31 pass through water, only the spray nozzle 32 does not pass through water, and the water flows from the three spray heads 31. The conveyor will continue operating until the coal mine is extinguished. When the infrared thermometer 27 detects that the coal mine temperature is lower than its ignition point, the internal temperature detection module of the infrared thermometer 27 will shut down, the pressure pump 26 will be de-energized, the water flow will become gentle again, the internal third signal transmission module of the infrared thermometer 27 will be de-energized and transmit a signal to the programmable controller 21. The programmable controller 21 will then transmit a signal to the first stepper motor 6 and the second stepper motor 20. The first stepper motor 6 will stop rotating again. At this point, the conveyor can only be turned on and continue operating after the staff confirms the situation. The second stepper motor 20 rotates 30 degrees again. At this time, the rotating disk 37 rotates 30 degrees. All three second through holes 35 are blocked by the lower end of the straight water pipe 18 and cannot pass water. The first through hole 33 is interconnected with one of the third through holes 36 and can pass water. The other two third through holes 36 are blocked by the upper end of the rotating disk 37. Indirectly, at this time, all three spray heads 31 cannot pass water, and only the spray head 32 can pass water. The three spray heads 31 and the pressure pump 26 can increase the water volume and make the water flow rapid, so as to extinguish the fire faster and achieve a strong fire extinguishing effect.
[0031] Example 3: When a ball lightning strikes a coal mine on conveyor belt 9, three coal mines instantly reach their ignition point and spontaneously combust. At this time, the three infrared thermometers 27 detect the temperature of the coal mine's ignition point, and water spraying begins to extinguish the fire at the three spontaneously combusting locations. Only the locations where the coal mine's ignition point temperature is detected will be pressurized and sprayed with water for fire extinguishing. Conversely, the locations where the coal mine's ignition point temperature is not detected will remain in a spray state. By setting up multiple branch water pipes 17, pressurized pumps 26, and infrared thermometers 27 in sections, the fire source can be quickly detected and water sprayed in a concentrated manner, achieving the effect of precise fire extinguishing and water conservation.
